Exploring disc galaxy dynamics using integral field unit data [PDF]
, 2008 In order to test the basic equations believed to dictate the dynamics of disc galaxies, we present and analyse deep two-dimensional spectral data obtained using the PPAK integral field unit for the early-type spiral systems NGC 2273, NGC 2985, NGC 3898 ...

Galaxy Dynamics in Clusters [PDF]
, 1995 We use high-resolution simulations to study the formation and distribution of galaxies within a cluster that forms hierarchically. We follow both dark matter and a gas component that is subject to thermal pressure, shocks, and radiative cooling.

Disk Galaxy Models Driven by Stochastic Self-Propagating Star Formation
Open Astronomy, 2010 We present a model of chemical and spectrophotometric evolution of disk galaxies based on a stochastic self-propagating star formation scenario. The model incorporates galaxy formation through the process of accretion, chemical and photometric evolution ...

Gas dynamics in the barred Seyfert galaxy NGC 4151 -- II. High-resolution HI study [PDF]
, 1999 We present sensitive, high angular resolution (6" x 5") 21-cm observations of the neutral hydrogen in the nearby barred Seyfert galaxy, NGC4151. These HI observations, obtained using the VLA in B-configuration, are the highest resolution to date of this ...

Kinematics and dynamics of the M 51-type galaxy pair NGC 3893/96 (KPG 302) [PDF]
, 2007 We study the kinematics and dynamics of the M51-type interacting galaxy pair KPG 302 (NGC 3893/96). We analyse the distribution of the dark matter (DM) halo of the main galaxy in order to explore possible differences between DM halos of "isolated ...

Reducing biases on H0 measurements using strong lensing and galaxy dynamics: results from the eagle simulation [PDF]
, 2017 Cosmological parameter constraints from observations of time-delay lenses are becoming increasingly precise. However, there may be significant bias and scatter in these measurements due to, among other things, the so-called mass-sheet degeneracy.

Simulations of the dynamics of magnetized jets and cosmic rays in galaxy clusters [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Feedback processes by active galactic nuclei in the centres of galaxy clusters appear to prevent large-scale cooling flows and impede star formation. However, the detailed heating mechanism remains uncertain.

Made-to-measure modelling of observed galaxy dynamics [PDF]
, 2017 Amongst dynamical modelling techniques, the made-to-measure (M2M) method for modelling steady-state systems is amongst the most flexible, allowing non-parametric distribution functions in complex gravitational potentials to be modelled efficiently using ...

A Comparison of Supermassive Black Hole Mass of NGC 4151 Using Different Methods
Passer Journal, 2020 We found a new value of supermassive black hole (SMBH) mass in the middle of type 1 Seyfert, NGC 4151 galaxy. In this Study, the image of NGC 4151 galaxy was deprojected to face-on, using spiral galaxy of face-on, and applied IRAF to calculate the ...
